| Abstract | In this paper, we present a Python-based software package that enables the conversion of numerical models from FEFLOW, a commercial groundwater flow, mass and heat transport modelling software, to OpenGeoSys, an open-source software for the simulation of thermo-hydro-mechanical-chemical (THMC) processes in porous and fractured media. This converter enhances interoperability in complex workflows for environmental geotechnics, as multiple software packages are now available for use at different stages of the workflow, thus combining their individual capabilities. We verify the software’s correct implementation with various test cases that cover the converter’s entire feature set: different physical processes, various boundary conditions, and source terms. The conversion software permits the modification of FEFLOW models post-conversion, which we demonstrate with a real-world example. The converter offers flexibility that extends beyond the modelling approaches in FEFLOW by allowing the use of OGS features. Thereby, it is possible to combine the advantages of FEFLOW, such as the model setup capabilities, with simulations of processes that only OGS supports. The presented software enables users to convert FEFLOW models to widely used open formats such as VTK and XML, fostering collaboration in research and application projects. Furthermore, using an open-source code like OpenGeoSys for simulations enhances the transparency. Geological models of porous and fractured media in open-source formats facilitate the transfer of data and knowledge within large research initiatives, particularly in complex domains such as nuclear waste management. |
